I hope so. Binance as far as I know still uses legacy addresses, and so do a few other large exchanges. If they finally hop on board, the rate of SegWit adoption will increase and the fees decrease.

If Coinbase can utilize SegWit swiftly, there is no reason other exchanges won't be able to do the same. Obviously, the services Roger and Bitmain are involved in won't be allowed to upgrade, but that's their loss at the end of the day.

I saw a review of the BlueWallet for LN and will give it a try this weekend. Hope that the current state of the network routes the payments more reliably than the last time I tried sending LN transactions.
